Good picture, but parallel lines? A bit dark at the bottom; stringy things at the edges of the petals make me suspect that this might be an artifical flower.
Overall, I like the image, composition, lighting, etc. The only thing I notice is a bit of grain and noise. I'm not sure if there would be anything you could do to fix it. I shotwild macaws when I was in Costa Rica last year and the same thing kind of happened to me (using a 35mm camera, no less). There's something about the colours and the light. But, anyway, good shot and I hope you do well.
